Optimal Utilization of Solar Energy for Electric Vehicles Charging in a Typical Microgrid

TLDR: In this article, the authors presented a charging management program to increase the penetration of renewable energy resources in a smart distribution grid and decrease the consumers' dependence on conventional power grids with fossil fuels.

Abstract: During the past few years, the growth of the greenhouse gas emissions and the global warming from fossil fuels to produce the electrical power, transportation, as well as the finiteness of these resources have become the most critical concern of governments to find the alternative resources for fossil fuels. Solar energy is one of these resources which are clean, unlimited, and completely free resource. However widespread use of that needs to make some changes in the power system thus due to its random production of electrical power, solar energy will be a great uncertainty in power system. Therefore, the power grid will be required to the reliable compensator, which compensate the lack of power by help to the generation sector when the production and consumption is imbalanced. The solution of this problem is energy storage and the flexible loads which have the ability to adjust power consumption and reducing it in the real time. Also transportation is one of the main sources of environmental pollution, to this end, PHEV is presented, but the widespread use of them will be creating a significant load on the grid. For this reason, the managing of these loads is required in order to increase permeability of renewable energy resources (solar energy) in a smart distribution grid and decrease the consumers’ dependence on conventional power grids with fossil fuels. Additionally, the chapter develops a charging management program to increase from renewable resources for penetration. The finding show that, this program is made to increase use of renewable energy resources by consumers and reducing received power of the conventional generation.
